► Made by UK firm Qwest► Fully functional sensors and features► £70,000 for the conversion – without donor car price included

Last month we wrote about not one, but two Tesla Model S estates. The first was the RemetzCar Model S Shooting Brake, and the second was the UK-built Qwest Model S estate. Now the latter is actually finished, and has pictured been out and about – complete with dog in the boot.

Called the P90D-SB, the new car features an extended, but slightly squared-off roofline. If the RemetzCar we saw last week was more of a Mercedes Shooting Brake, the Qwest Model S estate appears to be more of a Volvo V90.

Apart from the roof, the Model S estate keeps the design language of the original P90D it’s based on, and Qwest also claims all the features and sensors on the stretched Tesla are still functional, too.

According to Qwest, the Tesla Model S estate is actually 14kg lighter than the stock saloon car, thanks to the abundance of carbon-fibre at the rear.

As for the price? There isn’t one yet, but the conversion on its own cost £70,000 to complete. The only caveat? That doesn’t include the price donor car you want to do it to, and if you want the full Tesla experience, it won’t be cheap.

The RemetzCar Tesla Model S Shooting Brake

The newly tested Audi RS4 might be one of the most impressive fast estates around right now, but it’s about to get some competition from an unlikely source. That’s because a Shooting Brake version of the Tesla Model S has been unveiled, and it should be here by March 2018.

Firstly, it’s worth pointing out that the new Model S estate hasn’t been approved by Elon Musk in any way. Instead it’s an unofficial design, created by Dutchman Niels van Roij along with his London-based team. Secondly, the car won’t be made by Tesla either, and will see Model S electric cars converted by the RemetzCar coachbuilding company in Amsterdam.

Keeping the Tesla Model S DNA

Despite its third-party origins, we’d say the new Tesla Model S Shooting Brake looks extremely stylish. The front of the electric estate is relatively untouched compared to the original Model S, and it’s only the roofline that gets a modification over the stock EV. It’s more stretched than the original car’s, allowing room for an extended boot.

Apart from that, the standard Tesla Model S is untouched, so the Shooting Brake keeps the same rear lights and rear shoulder shape. No modifications have been made to the powertrain either, despite a likely increase in weight.

‘The conversion merges seamlessly with the Tesla base vehicle, while clearly communicating through form, design language and materials that this is a tailor-made Shooting Brake,’ van Roij said.

‘Of course, we added a completely new sculpted rear end, keeping the shoulders of the car alive, thus ensuring a bold stance.’

Bet there won’t be many Model S estates..

There’s no price for the Tesla Model S Sportback just yet, but with only 20 examples destined to be made, you can expect to pay a heavy premium for one.

Why isn’t Tesla making its own estate?

While the Model S Shooting Brake unveiled this week is unofficial, it’s probably only a matter of time before we’ll see one made by Tesla themselves.

In the last few years, Tesla has varied its range of models to include the premium Model X SUV, Model 3 mid-range saloon and most recently the Roadster hypercar. Is it only a matter of time before Tesla introduces an estate of its own, too? Or will the genre’s relative unpopularity in the US mean this is destined to remain a coachbuilt special?
